TRIPLE TH ERMiC MOTOR.

SPECIFICATION forming part Of' Letters Patent No. 432,511, dated July 22, 1890.

Application led January 13, 1885. Serial No. 152,714. (No model.)

To all' whom t may concern.'

Be it known that I, WILLIAM S. CoLwELL, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Triple Thermic Motors; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Hy invention consists in the means hereinafter described and specially claimed whereby a motor is generated by the induction of liquid bisulphide of carbon into a vapor-generator and circulating it therein, said generator being contained within a steamboiler, and subjecting said liquid to heat contained vwithin said steam-boilerto evolve vapor, and also superheating and expanding said vapor in a chamber orreservoir contained in said steam-boiler, thereby increasing` its tension and maintaining the heat and expansion of said vapor until it has performed its ofce on the piston of the engine, and also automatically controlling the induction of said liquid into said generator, and also automatically controlling the pressure of said vapor, and also conveying the vapor exhausted from the engine to the condenser, and also returning the liquid bisulphide of carbon to said generator heated to about the boiling-point.

To enable others skilled in the art with which my invention is most nearlyconnected to make and use the same, Iwill proceed to describe its construction and operation.

In the accompanying drawings, which form part of this specification, Figure 1 is a vertical section of an apparatus for carrying out the invention stated, and hereinafter more fully described. Fig. 2 is a horizontal section of the steam-boiler, representing a plan of the bisulphide-of-carbon vapor-generator and expanding chamber contained within said steam-boiler. Fig. 3 is an enlarged View of the regulating-valve for controlling the flow of the liquid bisulphide of carbon to the pump. (Shown in side elevation.)

Reference being had to the accompanying drawings, A represents an ordinary furnace for the tubular steam-boiler B,'which`is also of ordinary construction and furnished with the usual appendages of such boilers.

Above the tubes C is arranged within the boiler B a generator D, which is of uniform diameter from the rear end of the boiler t0- ward the front end, running zigzag', as shown in Fig. 2, and communicates with avapor-superheating chamber E, having conduit F for conducting the vapor to the cylinder Gof the engine, havin g a casing around it, which communicates with the casing I-I around the conduit F, supplied with steam from the boiler. This incasing of the cylinder G and conduit F is clearly and fully described and shown in,

Letters Patent No. 219,622, granted to me September 1G, 1879, in which patent is also described and shown a steam -boiler having within it a generator for evolving liquid bisulphide of carbon into a vapor for a motor.

The conduit F is provided with a valve I and safety-valve J, to which is attached a pipe K, which communicates with the condenser L, which communicates with a vacuum-pump M. Substantially this arrangement of safety-valve, condenser, and a vacuum-producing mechanism, and the purpose and operation of the same is also described and shown in said cited patent. The throttle-valve N and lubricating device o, connected to and communicating with the cylinder G, are also described in said cited patent and in Letters Patent No. 266,952,1granted to me October 31, 1882.

The generator D is arranged on a horizontal plano; but part of it may be arranged at an angle to said plane, as indicated by dotted lines. (Shown in Fig. l.) The rear end 0f the generator D communicates with a pipe P, which enters and is arranged in a heater R and communicates with a pump Q. This arrangement of pipe P, heater R, and pump Q, and the purpose and operation of said parts are fully and clearly described in cited Letters Patent No. 266,952. The lower end of the heater R communicates with the exhaust of the cylinder G through the medium of pipe T, and its kupper end communicates with a pipe U, which communicates with the condenser L, which communicates by pipe W' with the vacuum-pump M, whichcommunicates by pipe X with a washer V. The condenser L also communicates with awell Y, which communicates by a pipe a with a balance-valve E', which by a pipe c communi.

cales with the pump Q. The balance -ralre Il is opened and closed by the regulatingvalve A', having.chambers ll C', diaphragm D, plunger li", level' G', and weight Il', said valve communicating with the conduit l" by means of a pipe I), which is charged with water to about the dotted line e.

The vacuum-pump, washer, condenser, well, pump Q., balance-valve, and regulating-valve are all substantially as shown, described, and claimed, and their operation and purpose fully set forth in my application for Letters Patent tiled July 2li, lSSl, Serial No. 1.352810, and therefore not herein claimed, and need not be further described in this specification.

The casing surrounding the cylinder G comlnunicates with a steam-trap f, through the medium of pipe g, and said trap communicates with the pump 7iy by means of pipe i, and said pump zy communicates with the steam-boiler B by means of pipe i. The packing mechanism for the. valve-rod and piston of the cylinder communicates with the well Y by means of the pipes 7u 7n, as described in said cited application. The water in the boiler l may cover or partially cover the generator D, or the water may be below the said generator and the chamber E will be surrounded with steam.

The construction of the apparatus shown in the accompanying drawings and hereinbefore described will readily be understood from the foregoing description and by reference to the said cited patents and application.

I willtherefore proceed to describe the op eration, which is as follows: The boiler ll being filled to the desired point with water and the generator D charged with a sufficient quantity of liquid bisulphide of carbon for evolving vaporenough for starting the engine, and the well Y charged with the desi red quantity of liquid bisulphide of carbon, tire is then started in the furnace A, which heats the water in the boiler B and evolves steam therefrom, which heated wateror steam acts on the walls of the generator D and the steam surrounds the superheating-chamber E,so that the liquid bisulphide of carbon is evolved into a vapor in the tubes constituting the generator, and snperhcated and expanded in the chamber E and its tension increased. The operator opens the valve I and throttle N, and the engine is thereby put in motion. The vacuumpump beingput in motion, the exhaust-vapor from the engine passes through the pipes T, U, and K to the condenser L, and is condensed into a liquid which flows into the well Y, and from it through valve E to pump Q, which forces it through pipe I in the heater R, where the liquid bisulphide of carbon is heated by the exhaust-vapor from the engine to about the boiling-point in its passage to the generator D, through which it circulates, and is evolved into a vapor and superheated, and consequently has its tension increased in the chamber E, and passing from said chamber enters the conduit F and passes to the cylinder where, performing its oilice, itis exhausted into pipe 'l and makes the circuit, before described. The casing ll and casing around the cylinder receive steam from the boiler l5 through the mcdiuln of the pipe l, thereby maintaining the expansion and tension of the vapor until it has performed its oilico on the piston of the engine. In case the pressure of the vapor in the chamber ,E should be greater than determined upon, it will, through the pipe h, act against the water in the said pipe, which acting against the diaphragm D and it against the plunger Il will move the lover l', which will force down the stem m, and thereby close down the balance-valve E in accordance with the overpressure of the vapor, therebyvcorrespomlingly cutting off the supply of liquid bisulphide of carbon from the pump Q and generator l) until the pressure of Vapor in the chamber E has decreased to that pressure fixed upon by the operator. The weight ll will then open the balancevalve E and allow the desired quantity of liquid to flow to the pump Q` and generator D. The hot water produced by the condensation of steam in the casing of the cylinder G and casing Il of the conduit F will flow into the trap j" through the pipe g, and from said trap to the pump 71., which forces it through the pipe if into the boiler I3 at about the boiling-point. The condcnsable and incondensable gases which are drawn bythe vacuumpump through the pipe IV are forced through pipe X into-water in the washer V, as and for the purpose described in said cited application. The safety-valve J, which by pipe l( communicates with the condenser L, is for the purpose of allowing the surplus vapor in the case ot' overpressure to escape to the condenser L. The pressure of steam in the boiler l and the pressure of the vapor in the chamber E are shown by gages `n.

In another application tiled this day, Serial No.' 152,713, I have claimed the methods involved in generating a motor from liquid bisulphide ot' carbon, the claims in both applications having been originally presented in my application, Serial No. llOGQ, tiled August 10, 1884, and in which division was required by the Patent Office.

llaving thus fully described my improvement, what I claim as of my invention is- Il. 'lhe combination of a stean'i-boilcr, a va-y por-generator, a superheating-chamber of greater capacity than the generator contained within the boiler, and suitable means for supplyingliq uid bisulphide of carbonto thegencrator and the vapor to the engine, substantially as described.
